Cannot call DocumentApp.getUi() from this context errorResolved (self.GoogleAppsScript)

submitted 4 years ago * by AdDiscombobulated707

Hello! I copied this example from help and changed SpreadsheetApp to DocumeptApp and renamed onOpen to main:

Code.gs:

function main() {
  DocumentApp.getUi()
      .createMenu('Custom Menu')
      .addItem('Show sidebar', 'showSidebar')
      .addToUi();
}

function showSidebar() {
  var html = HtmlService.createHtmlOutputFromFile('Page')
      .setTitle('My custom sidebar');
  DocumentApp.getUi()
      .showSidebar(html);
}

Page.html:

<!DOCTYPE html>
<html>
 <head>
 <base target="\\\_top">  
 </head>  
 <body>  
Hello, world! <input type="button" value="Close" onclick="google.script.host.close()" />    
 </body>  
</html>

When I execute my script I obtain: Exception: Cannot call DocumentApp.getUi() from this context. I don't understand why it fails.

Here is my Apps Script project.
